Some of the actions that Windows services implements with C + + code-1: Modifying service startup types

VOID Dosvcstarttype () {Sc_handle schscmanager; Sc_handle Schservice; Get a handle to the SCM database. Schscmanager = OpenSCManager (null,//local computer NULL,//servicesactive database sc_manager_all_access); Full access rights if (NULL = = Schscmanager) {printf ("OpenSCManager failed (%d)/n", GetLastError ()); A handle to the service.

This is the startup type code for the Modify Windows service implemented by C + +. The friend of hobby supports a bit.
